Product of the Reaction of Activated Industrial Aluminum Alloys with Water as a Precursor of a Catalyst Support

Products of the reaction of water with technical aluminum alloys activated with Ga–In eutectic were obtained. The major impurities in the aluminum hydroxide formed are Ga (5 wt %), In, and Cu (0.6–0.7 wt %); Fe, Zn, Ca, Mg, and Mn were also detected in amounts less than 0.1 wt %. A procedure was sug...

Description
Summary:Products of the reaction of water with technical aluminum alloys activated with Ga–In eutectic were obtained. The major impurities in the aluminum hydroxide formed are Ga (5 wt %), In, and Cu (0.6–0.7 wt %); Fe, Zn, Ca, Mg, and Mn were also detected in amounts less than 0.1 wt %. A procedure was suggested for purification of the contaminated Ga–In eutectic used for the Al activation with the aim of subsequent reuse of the eutectic. The oxide phase obtained from the synthesized product is γ-Al 2 O 3 modified with Ga and In. It is characterized by the developed surface (surface area ~300 m 2 g –1 ) and mesoporous structure; it can be used as an adsorbent and support for dehydrogenation catalysts. Platinum catalyst on the oxide support obtained is comparable in propane dehydrogenation performance to model systems based on А0 aluminum alloy.
